Title: Use of a polyol to improve the rate of low pressure - synthesis of ammonia
IPC: C01C1/04
Filed: 1969-05-16
Abstract: The rate of production of ammonia from its elements at lower pressures than normal (i.e. below 150 bars) can be effected without an increase in gas flow rate if the gas is continually scrubbed out in a non-volatile solvent. Various glycols and glycerols are very suitable. The solvent system need not be water free provided that the water vapour content of the reaction gas is kept to a minimum, and a hygroscopic solvent is of advantage since it can serve to remove water vapour from the gas stream which would otherwise tend to impair catalyst performance. The solvent can be readily regenerated by heating or by rectification with a gas stream, the evolved ammonia then being trapped by a convenient process suitable for its final intended use.

Title: Gripper release - by cam piece which operates only after weft insertion
IPC: D03D47/23

Title: Thin filter sheet support - has line contact with sheet to permit filtration over full sheet area
IPC: B01D35/143
Filed: 1972-05-29
Abstract: Filter of the type using a thin filter sheet (4) formed as a sleeve with a reinforcing support (8) on the upstream face of the sheet and fitted inside a case (1) with an inlet (2) and outlet (3) separated by the sheet; essentially the support (8) has only linear contact with the sheet, being made, preferably, as a single continuous wire of round cross-section, e.g. as a helical coil spring with spaced coils. Particularly for industrial filtration of pressurized gases and liquids. The full area of the filter sheet is employed to advantage as the line contact support (8) does not impede the flow of fluid to be filtered. On the other hand, the support provides the sheet with adequate reinforcement to withstand high pressures, yet is cheap to produce and easily fitted.

Title: Feed mechanism for supplying one or more identical objects - is operated cyclically by electro-magnet in high speed low power system
IPC: B65G59/06
Filed: 1973-10-23
Abstract: The objects such as ball bearings, coins or spring etc. are released one at a time from a tube through the feed mechanism to another tube and from there elsewhere for further processing. A solenoid on each cycle pushes forward the armature which simultaneously pushes forward the release pin and the stop pin. In the position shown objects are held back by release pin. On movement of the armature to the right the stop pin will grip the object after which spring compresses while the armature continues to move until release pin abuts on adjustable screw. At this point the hole in pin is aligned with hole and one object can fall through. For objects of different length, or for releasing several at a time, the centre distance between the two pins can be changed.
